Application filed' August 10,1921. 'serial No, fiancee.

My invention relates @improvements automatic means `for ldisconnecting.; a r'oll train from the driving' means.

In roll trains in rolling mills 4there are al-V Ways Inainguides over which iron or steel passes but it often happensthe same passes under the guides and in which event collars are formed yin the grooves of the'rolls. The forming of these collars often resultin the breaking of the roll spindle or rolls yasthe breaker devices usually employed are not adequate toy relieve the undue pressure;v

i; The objectvoffniyfinvention 'isto provide means extending into the grooves of the rolls and operated by any collar Vformed therein,

t* to operate the connecting means'betweenthe l vide a device oi this character' which can be steel therethrough Will stop the entire seriesr driving means and the rolls, so as to Ydiscon'# nect'the roll froin'the driving means and stop the same, so that another bar of iron or steel Will pass throughthe machine,

" Anotlierobjefct or" my invention is' to proreadily applied to theordinary forni oi? 'roll train Without any changes'l thereof or any changes in the form of disconnecting'ineans ordinarily used 'and operated by hand. Y y l Astillfurther object of my invention is to provide means yivlherehy -a series of roll trains may he'driven` by a single engine yand in which improper passage of thel bar ofiron or andat the same time providing means 'at each sider ofeach roll train, in easy reach of the operatorto` 'cause rvthe-disconnet-:ting of the engine `from the rllt'rains.A y

Other and further objeetsa'nd advantages of the invention lWill behereinaiter set `forth andthenovel features thereof defined by the appended claims. f i

Figure 6V is a side di.agraininaticalvievv` showing the series `of roll sets comprisinga roll traina and o e Figure 7, is an end elevation shovving means for holding thev operating lever in engagement with the clutch.` y

Referring' noifv to the drawings, l represents the housing of a roll set which as sliovvn l consists of the three groovedrollers,` 2;-3 and 4 and which are rotated in anypof the'ivell known manners know-n tothose skilled in the art and needs no further description vasthis r' forms no part of my invention.

, The rolls 'as shown are mounted in :the housing l as shown i'nFigu're land carried by the housing are the tivo oscillating bars or shafts 5v andy 6 which `extend entirely across the housing `parallel with the rolls. Rigidly Acarried by the upper slhaft are the guides?v as shown in Figure L ofv 't-hedravv-Y ings which extendover the upper faoeof the roll'Q- and turn downwardly at 8` and closely fit. the bottoni ofthe grooves 9.l y Y Y As shown iii F'gure l of theV drawings, there is a guideior Aeach groove in the r'll 2 so that if a collar forrnsin any Vgroove the roll train is stopped. The guidel' and the d'cuvntvardlyv turned portion' are made separate and secured together Eyt'heiiOlts lO'so .that they can he adjustedtofclosely engage the bottom of the groOv'ee'.` These bolts eX-A -teiid through slots 11 in the portions' se that the Vguides canbe moved longitudinally so that they canbe adjusted to engage thebottom of the grooves. Y. y

Carriedby'dthe lovver shaft ti are the rigid guides 12 which .enter the-groove i3 in the loiver roll Thesefguides are rigid and need no adjustmentV 'as they can be made to engage" the bottomof the grooves 131'in the roll t andl theupper set' of guidesthen adjusted., g l

vided Withv outwardly extending rigidl arnis 14 andlr 'tvhic'h'ha've tlieirlouter endsbiftin cated and formi-ng adjustable connections 16 and 17 by means of which tlieyare con; nected tothe '1 rod 18 ,whereby either guide will operate the rod, These connections as formed by the shafts 19"and: nuts 20"a`nd 21 and setA screw 22. 'Theloltverfbolt 19 vextends outwardly beyond the lrodal'id carriesan up- Wardly extending arm 23, vvhieh carries a cam 24adapted to trip the catch 25, which I will now proceed to describe.

The catch 25 is pivotally supported between the arms 26 and 27 ofthe bracket 2S by the pivot 25, which is carried by the end of the frame 1 as shown in Figure 2 of the lrawings. The catch 25 has the hooked end Z9 which extends through the looped end 30 if the spring 31 and which holds the spring in its expanded position as shown in Figure 2 of the drawings, and the function of the spring will be later described.

The catch has a downwardly and outwardly extending portion 32 which extends downward in the path of the cam 24 and whereby the catch is rocked on its pivot transverse thereof. T his is accomplished by having the arms 2G and 27 spaced some distance from the catch and having` the openings through the catch beveled as indicated in dotted lines at 33, Figure 3.

In order to hold the catch against its swinging movement on its pivot, I provide a latch 84 rigidly carried by the braclret 28 and extending around 'the latch 'fully shown in Figure 2 of the dra.vings.

Connected to the loop ot the spring 31 is a cable or chain 35 which extends upwardly over the pulley 3G carried by the frame 37 and which extends rearwardly, over a secon-d pulley 38 carried by the trame and extends downward and is adapted to operate the clutch 39, which disconnects the drive shaft 4() from the engine or motor (not shown).

In operation the formation of a collar in either of the rolls 2 or 4 will cause the guides 7 or 12 of Figure 4 to ride upon the collar rocking the shafts o and 6 causing the cam 24 to engage the catch 25 rocking it on its pivot transverse the pivot to move the catch to Yone side beyond the latch 34. The catch 25 is then free to swing down on its pivot and the tension of the spring draws the catch downward and at the same time pulls the cable or chain 35 downwardly and operates the clutch member 39` ot the clutch 39 to disconnect the drive shaft 4() of the roll train from the drivingl means or engine and thus stops t-he rolls as shown and described in my application filed September 15, 1921, Serial No. 522,567. After this operation the portionl oit the collars formed in the groove or grooves of the rolls are removed and the machine again started.

In order to reset this operating means, I provide the frame 37 with a pulley 41 over which passes the chain which extends down and has a connection with the loop 3() of the spring 31 whereby the spring may be expanded or drawn upwardly sov that the catch 25 may be passed into the loop 30 and the latch 34 Set to hold the spring under compression.

In order to hold the guides 7 and 12 in the grooves in the rolls 2 and 4, I provide a spring 43 which has one end bearing against the housing 1 as shown in Figure 3 of the drawings and its opposite end bearing` against the cam 24. The outer end of the spring is provided with a rivet loosely entering the same and upon which may be placed washers 43 for varying or increasing the tension of the spring.

In Figure 1 I have shown my invention as applied to a single roll set but as a rule they are arranged in series and in Figures 5 and 6 I have shown the cable 25 corresponding to 35, Figure 1, having the cables 44, 45, 46 and 47 connected yto the guides ot' the dillerent roll sets and whereby the series of rolls are stopped upon the operation of any of the guides.

In order to stop the rolls by hand I provide chains or cables 4S, 49, 50, 51, 52, 53, 54 and 55, which extend over pulley and extend down on eacn side of the machine in reach ot the operator. These cables are connected Ito the cable 35, Figure 1, and whereby the entire series of rolls can be stopped by the operator of any of the series of rolls from either side.

That I claim is 1. rIlhe combination with a roll train, guides in the grooves of said rolls, and means operated by said guides when collars are formed in the Orooves 'for stopping the roll train.
